also im working with the default settings.... No core image enabled!

Im a developer myself, and this looks pretty much as a memory leak.... The applicatino starts using around 26 mb, and after a few hours of use, it grows to big numbers.... Have you tried running it under malloc debug? it's a very handy tool for finding leaks... good luck! Im sure it's something very stupid....

I totally understand this kind of problems at early stages (as those are preview releases)..... It was more like a beta-tester suggestion...

I bought your software a few weeks ago (when i got my macbook pro), it's so useful! :)

best, oriol
